我如何把php得到的数据进行分类呢?
<?php$con = mysql_connect("localhost","root","123");if (!$con) { die('Could not connect: ' . mysql_error()); }mysql_select_db("task", $con);mysql_query("set names utf8");$result = mysql_query("SELECT * FROM tesk limit 0,10 ");echo "<table border='1'><tr><th>time</th><th>id</th><th>name</th><th>task</th><th>remark</th></tr>";while($row = mysql_fetch_array($result)){ echo "<tr>"; echo "<td>" . $row['date'] . "</td>"; echo "<td>" . $row['id'] . "</td>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['task'] . "</td>"; echo "<td>" . $row['remark'] . "</td>"; echo "</tr>"; }echo "</table>";<a herf=“”>下一页</a> mysql_close($con);?>
新手,求各位同仁指教

你可以从数据结构上进行分类,你现在的表字段是 日期,ID,姓名,工作,备注, 你可以再加一个分类,然后在做数据添加的时候,就要先把这条数据归于哪一类做好,这样以后你要获取哪一类数据就很容易了。

分页,大神,求源码
我以前写的分页,现在去看已经看不明白了。代码供参考:
class PageTool{ protected $total=0; protected $perpage=10; protected $page=1; /*构造函数的参数分别为商品总条目数,每页多少条目,当前页*/ public function __construct($total,$page=false,$perpage=false){ $this->total = $total; if($perpage){ $this->perpage = $perpage; } if($page){ $this->page = $page; } } public function show(){ $cnt = ceil($this->total/$this->perpage);//$cnt表示一共需要多少页 $uri = $_SERVER['REQUEST_URI']; //从地址栏获取URL $parse = parse_url($uri); //将获取的URL变成特定数组 //print_r($parse);exit; $param = array(); if(isset($parse['query'])){ //如果地址栏传了参数(也就是url?之后的字符串),则获取参数放入$param数组中 parse_str($parse['query'],$param); } /*不管地址栏有没有传page参数,都要把page从$param中剔除 因为page参数是需要计算出来的,不能定死*/ unset($param['page']); $url = $parse['path'].'?'; if(!empty($param)){ $param = http_build_query($param); //把数组$param再变成字符串,这一次已经剔除了page参数 $url = $url.$param.'&'; //重新拼凑$url,最后的&符号用于连接计算出的page } /* 关键部分:计算页码导航 此处逻辑有点复杂,多思考下 */ $nav = array(); //用于存放最终地址栏链接 $nav[0] = '<span class="page_now">'.$this->page.'</span>'; //把当前地址栏的page参数放入$nav数组 for($left=$this->page-1,$right=$this->page+1; ($left>=1||$right<=$cnt)&&count($nav)<=5;){ if($left>=1){ array_unshift($nav, '<a href="'.$url.'page='.$left.'">'.'['.$left.']'.'</a>'); $left-=1; } if($right<=$cnt){ array_push($nav, '<a href="'.$url.'page='.$right.'">'.'['.$right.']'.'</a>'); $right+=1; } } return implode('', $nav); }}/* 测试分页类效果 $page = isset($_GET['page'])?$_GET['page']:1; $pagetool = new PageTool(20,$page,6); echo $pagetool->show();*/
